SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 299,719, dated June -3, 1884.

Application filed January 16, 1884. (No model.)

.To a/ZZ whom it may concern..-

Beit known that I, GEORGE S. BAENEs, aV

citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specication, reference being had to the accompanying drawings.

My invention relates to a combined sash lift and fastener; and it consists in a flat spring, fastened at one end to a fixed stand and at tached at the other end to a swinging and sliding bolt, in combination with xed fingerplates, as hereinafter described, so that by pressing the spring up or down the bolt will be withdrawn from a catch, and by continued pressure in the same direction against the spring and a finger-plate the sash will be raised or lowered.

In the drawings, Figure 1 is a front view of part of a window frame and sash having a device attached thereto embodying my invention. Fig. 2 is a plan view. Fig. 3 illustrates the construction of the bolt-guide.

On the front of the lowerrail, A, of the sash I fasten a plate, B, having iiXed thereto two projecting nger-plates, C and D. These iinger-plates should be some distance apart, one above the other, and near the longitudinal cen` ter of the sash-rail. A projecting stand, E, is also xed to the plate B, this 'stand and the nger-plates having the relation to each other substantially as shown. I fasten a rack, F, having, preferably, V-shaped projections and grooves on the side of the window-frame G. To the stand E is fastened one end of a at spring, H. The other end of this spring is joined to one end of a bolt, I. This bolt may swing in a vertical direction and slide in a 4o stand and guide, J, fastened to the sash' near the other end of thebolt., The stand and guide J has a taper recess to receive the bolt and allow the necessary motion thereof. In Fig. 3, which shows a section of the projectingpart of this stand, the form of the recess is illustrated. The spring acts to maintain itself and the bolt in a straight line, and hence to keep the outer end of the bolt in a groove in the rack, the sash being thus held in any required position. By pressing against the under side of the spring itwill be bent upward against the linger-plate O and take the position illustrated by the dotted lines at a, carrying the bolt into the position indicated by the dotted lines at b. Thus the end of the bolt will be withdrawn from the groove in the rack. By continued pressure in the same direction against the spring, and hence against the iinger-plate O, the sash will be raised. The bolt may be withdrawn from a groove in the rack and the sash be lowered by pressing, in a similar manner, downward against the upper side of the spring and the nger-plate D, the spring taking the position illustrated by the dotted lines at c and the bolt by the dotted lines at d. One movement of the hand will thus withdraw the bolt and raise or lower the sash, and but one hand will be required for the operation.

My invention is especially designed for carwindows; but is also applicable to other windows, and may be adapted to blinds.

I claim as my invention- The combination of stand E, finger-plates C and D, flat spring H, bolt I, guide J, and rack F, said spring being fastened at one end to said stand and at the other end to said bolt, substantially as and for the purposes set forth.

GEORGE S. BARNES.
